>Try setting the Enabled property for the listview to .F. before you set the height to 99999. I think all the loading overhead is in the drawing and clipping that is performed for each node.

Yes. I set Enabled = .f. before modificatin of the height property. But it is not restrict the repaint. FlexGrid for this feature have REPAINT property.

>Their is also a WIN32 message you can send to the listview and tree that will stop the update process until you tell it to. I will find the message for you.

It would be good ;) Thanks.
